Stylish Japanese Summer Fan Illustration

Create a stylish, contemporary Japanese summer illustration on a clean, white, vertical canvas, with a traditional round fan with a bamboo handle at its center. The fan surface should be in shades of cyan and dark blue, featuring layered, semi-transparent graphic shapes that blend ukiyo-e style patterns with modern poster design. Display six main decorative motifs on and around the fan surface: 1) a white flowing river or wavy ribbon that runs across the fan surface from the lower left corner; 2) green bamboo leaves clustered around the upper left edge; 3) morning glories on the right, including a large pink flower, a large dark blue flower, and several small dark blue buds; 4) round green leaves near the flowers and in the lower left corner; 5) a semi-circular, umbrella-shaped arc with cream and coral stripes in the background on the upper right side of the fan surface; and 6) abstract halftone dots, splatter marks, and diagonal geometric brushstrokes in cyan, bright green, coral pink, and dark blue around the fan surface. The fan ribs and frame are rendered as realistic light-colored bamboo, with numerous fine ribs radiating from the bottom. A delicate bluish-green ribbon connects the handle, and the natural bamboo handle extends downwards. A refreshing mixed-media style is employed: flat vector illustration combined with delicate paper textures, silkscreen halftones, translucent overlays, and subtle white vertical fan folds, with slight shadows added to give the fan a sense of depth. The composition remains ethereal and elegant, with ample white space. The date and artist's signature are added in the lower right corner, with the following text:{argument name="date text" default="May 15, 2026"} and{argument name="signature text" default="Oyagi"} The illustrations adopt an elegant and stylish atmosphere inspired by Japanese summer, with the main color scheme being {argument name="main palette" default="Cyan, indigo, bright green, white, coral pink"} No extra text, no watermark, no border.
